Ingredients & Substitutions
- quick oats – the key to a smooth creamy texture (besides the milk). Quick oats make it more batter-y with some texture. Use gluten-free oats or regular rolled oats, and if you don’t have quick oats, traditional rolled oats work too.
- protein powder — I use a scoop of vegan vanilla protein powder and a little bit of unflavoured pea protein powder to balance the sweetness out. Feel free to use other flavours or types of protein powder and adjust the amount you want to add. If you don’t have protein powder, nut and seed butter are always an option to add more protein, but you’ll have to dial back the liquid by about 1/4 cup
- Chia seeds — to make the batter “grow” and expand the size. Chia seeds also add fibre and lots of nutrients too. Flaxseeds are always a good substitute
- Milk & Water – any kind of milk. For high-cal and higher protein, substitute the water for milk. Makes the recipe extra creamy. The amount of milk varies depending on your oats and protein powder
- Optional: spices (I used cinnamon, cardamom, ground ginger),
- flavours (cocoa/matcha/coffee/acai powder, lemon zest, vanilla/mint/coconut extract, fruits, etc.)
Tips & Tricks for the best protein overnight brownie batter oats
- Mix the dry ingredients well
- Add a few fewer wet ingredients at first. Once it reaches a thick batter texture, add another tablespoon or two of milk. That’s because the mixture will thicken in the fridge
- I recommend letting the batter sit in the fridge for at least 3 hours for the best results
- and taste test!! Everyone has different preferences. Sweet tooths out there may want to add more sweetener, while people who love creamy textures may want to use higher fat-content milk and use oat flour instead of regular or quick oats
